Burai (as shown here )
was evil in
ZyuRanger however Bandora
didn't have access to the Coin for the powers because he already had
the Coin and the Dino Buckler whereas in Power Rangers, Rita already
had access to the Coin and she was the one who selected Tommy (as shown
here ) to be her evil
Green Ranger.

Now pretty much all Green
Ranger footage is Japanese except for the shots of him in the palace
and in the Command Center. Some Burai shots even snuck into
the Power Rangers episode because that was Japanese
footage of a guy lying down on a table in a foggy cobweb room, some of
his close-ups of his eyes was also Japanese footage which faded into a
close-up of Tommy's eyes.

Here are some shots in order
to compare the Green Ranger footage between ZyuRanger and Power Rangers.

Power
Rangers

All of the footage of Rita's
Skull (as shown here ) is ZyuRanger
footage. This episode also
marks the first American appearance of Rita Repulsa (as shown here )

All of those scenes as shown
in that image is new footage with Rita in it however the costume is
worn by an American actress which is why her face is hidden.
